STAND FOR CALORIMIETRIC BOMTBS.

Application filed August 31, 1926, Serial No.

My invention relates to improvements in and connected with the stands for 'alorimeh ric bombs, and has for its object to provide one of a simple and eihcient nature.

According to this invention. the stand is formed of three or any suitable number of arms of any suitable metal, the end of each of which is turned up forming as it, were a kind or": casing, in which the bomb sits and 10 slightly bent outwards atihe extreme'ends thereoi. Suitably attached to each arm or integral therewi h there is depending leg by which the stand rests on the bottom of the tank or container. the upper ends of said legs act as a support for the bottom of the bomb.

A pin slightly shorter than the legs so that it cannot come into contact with the bottom of the bomb is suitably attached to the centre of the bottom of the inside of the tank or container, the end of the pin passes through a hole or opening formed in the centre of the arse of the stand thereby fixing the position or the stand centrally in the bottom of the tank or container.

In order that my invention may be properly understood and readily carried into etfect, I have hereunto appended one sheet of drawings, of which Figure 1 is a sectional elevation showing the stand in situ in the tank or container and with the bomb placed on said stand.

Figure 2 is a plan of Figure 1 with bomb removed. 7

Referring to the drawings, A A A are the arms of which the stand A is termed, and B B and B are the bent-up portions which,

as shown in Figure 1, are turned outwards at.

the upper end to admit of the bomb C being more readily placed in the stand. pending legs'D D and D are screwed or otherwise sulbly attached to the arms A A and A of the stand A. D D and l) are the lower port-ions oi" the legs resting on the bottom of the tank or container E, while the upper portions as stated, project through the stand A in order to facilitate the free'cir- The de' 132,383, and in Great Britain March 30, 1928.

culation of water underneath the bomb C which rests upon them instead of on the arms. The pin F is screwed or otherwise suitab U fixed to the centre 01 the bot-tom of inside oi the'tanlr or container the upper end of which pin F engages with the stand A by passing through the hole or opening: F in the center of the stand A, thus ensuring: that the latter and consequently l l the bomb shal always be placed centrally in the calorimcte a condition which is esse- -.al "for accurate resuits.

From my improvements itwill be obvious that contact ot the stirrer with the bomb cannot occur as sometimes happens with other types of-stand since with them the bomb is placed in what in the udg'ment of the operator only the central position. If the bomb is wrongly placed it is necessary for the operator to adjust it which is a waste of time.

Time is also saved in adjusting the position or" the bomb in the calorimeter, since the form isalways put down in exactly the right place, consequently the operator need not waste time trying the stirrer or otherwise to discover whether the bomb is properly placed.

freer circulation oi water under the bottom of the bomb is permitted which is an important consideration since it is conducive to accuracy of results and my improvements are also suitable for use with any type of bomb or stirrer.

Claim:

Apparatus of he class described COllplii ing a tank having an upstanding centrally arranged pin in the bottom and a stand comprising radial arms united together at their inner ends and having at their point of union an opening for the reception of said pin, said arms having vertically arranged upwardly extending outer endportions, said stand also having depending legs secured to the said arms and bearing on the bottom of said tank.

In witness whereof I afiix my signature.

JAMES DARE-OCH.
